CosmoSurf® polymers are made from natural and renewable starting materials. The polymers are not made using traditional free-radical based polymerization processes and are therefore free of residual vinyl-type monomers, initiators and catalysts.

CosmoSurf® polymers are excellent film forming polymers that provide up to 80 minutes of water resistance in emulsions and (alcohol based) spray products. CosmoSurf® is a flexible polymer platform, resulting in the ability to create and modify aesthetics, as well as adding on multiple benefits, such as pigment dispersion and avoiding ‘white-out’ upon application onto wet skin that is common for free-radical based film forming polymers.

Optical microscopy images show that TiO2 pigment in Caprylic/capric triglyceride forms large clusters and agglomerates. In the presence of CosmoSurf® polymers (in this particular CosmoSurf® DDG-20) the TiO2 clusters are broken up and a more uniform dispersion is achieved.

​

The effect of CosmoSurf® polymers on the white-out effect is demonstrated by applying two alcohol-based sunscreen onto wet skin. When a traditional free-radical based film former is used the white out effect is clearly visible on the left side of the arm. When CosmoSurf® polymers are used as film former, the white-out effect does not occur (right side of the arm).

The multi-function character of CosmoSurf® polymers allows for the creation of simpler formulations as separate ingredients, such as aesthetic modifiers and dispersing aids can be eliminated.
